“Yet paragraph 122 of Mr. Lipoff’s declaration merely repeats the Petition’s argument almost verbatim. Compare Ex. 1007 ¶ 122, with Pet. 28. Mr. Lipoff does not add any citation to Avellan or any other source that supports his testimony. See Ex. 1007 ¶ 122. Nor does Mr. Lipoff offer any additional technical reasoning than what is stated in the Petition. Testimony may be entitled to little weight if it merely restates the petition’s unsupported, conclusory assertions without adding supporting evidence or technical reasoning. Xerox Corp. v.

“We are persuaded by Patent Owner’s argument that claim 1 is not obvious over Avellan because it does not assemble a media stream of multimedia items using the recited screen captures. See PO Resp. 21–23. We agree with Patent Owner that the plain language of the claim requires more than transmitting individual media items. PO Sur-reply 20. To the extent that Avellan captures images, those images do not meet the claimed requirements for a “temporal sequence of screen captures” in the independent claims, which must (1) be of the web page rendered by a browser, (2) “define all the content of the web page at a given time,” (3) “illustrate a dynamic change of at least a portion of the content over time” when two of them are compared, and (4) used to assemble “the at least one media stream.” Rather, the record better supports Patent Owner’s argument that Avellan transmits the multimedia items separate from any media stream assembled from screen captures.

“To establish inherency, the extrinsic evidence “must make clear that the missing descriptive matter is necessarily present in the thing described in the reference, and that it would be so recognized by persons of ordinary skill.” Continental Can Co. v. Monsanto Co., 948 F.2d 1264, 1268 (Fed. Cir. 1991). “‘Inherency, however, may not be established by probabilities or possibilities. The mere fact that a certain thing may result from a given set of circumstances is not sufficient.’” Id. at 1269 (quoting In re Oelrich, 666 F.2d 578, 581 (C.C.P.A. 1981)). Reasonable inferences of a POSITA may suffice to establish inherent disclosure in a prior art reference such as Farber. See Eli Lilly v. Los Angeles Biomedical Research Institute, 849 F.3d 1073, 1074–1075 (Fed. Cir. 2017) (“[T]he dispositive question regarding anticipation is whether one skilled in the art would reasonably understand or infer from a prior art reference that every claim element is disclosed in that reference.”).

“The Decision on Institution adopted Petitioner’s proposed level of ordinary skill in the art. Inst. Dec. 8–9. We find Patent Owner’s stated level to be less precise than that proposed by Petitioner in that the modifier “at least” used by Patent Owner imposes no upper bound on the amount of experience possessed by one of ordinary skill in the art. Also, Patent Owner states: “The difference between the Board’s definition and Patent Owner’s does not change the arguments set forth herein.” PO Resp. 5.

“We agree with Patent Owner that the district court’s construction is better than Petitioner’s proposed construction, because for reasons indicated by Patent Owner, which are not disputed by Petitioner, settings in the computer, e.g., dedicated folders for each user, are the user profiles, rather than simply data alone of any kind. Further, when asked about the appropriateness of the district court’s construction, counsel for Petitioner expressed that Petitioner has no objection to the Board’s adopting the district court’s construction for “user profile”: JUDGE LEE: So, you’d be fine with just going with the District Court’s construction? MR. HEINTZ: Yes, Your Honor. Tr. 15:22–24.

“We do not reach a resolution on the issue of relative cost between a wired LAN versus a wireless LAN, because Petitioner’s assertion that wireless LANs “were often cheaper and easier to install” is nebulous by use of the imprecise word “often.” “Often” cheaper permits “often” not cheaper. Much depends on how many access points would exist in the wired LAN. Petitioner does not discuss that consideration in the context of Horn. Also, we are persuaded by Petitioner’s other stated reasons for implementing Horn’s LAN as a wireless LAN: (1) that a wireless LAN can be more convenient to users, and (2) Baumgartner provides adequate motivation by disclosing transmission of video from server 36 via communications network 34 such as the Internet over link 48 implemented wirelessly to user computer equipment 22 such as a personal computer. Pet. 29–32. We are persuaded that a wireless LAN provides more user convenience by enabling the user equipment accessing the external network to be flexibly located within the range of the LAN without need to have wires installed to run to those locations. That is true whether there is only one user equipment or there are multiple user equipment, one per user. In the case of only one user equipment, the user can access the external network from a wide range of locations and change that location flexibly. In the case of multiple user equipment, one per user, each user can access the external network from his or her own preferred location, and also change that preference at any time without regard to whether wires have been installed to the preferred location.” slip op. at 22

“3. Analysis Only terms that are in controversy need to be construed, and then only to the extent necessary to resolve the controversy. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))). Both parties have presented their understanding of the plain and ordinary meaning of the terms “referenced to” and “independent of.” In the Institution Decision, we requested that “[i]f there is a dispute over the plain and ordinary meaning of these terms, the parties should address those issues during trial.” Dec. 14–15 n.6. On this record, the parties do not dispute each other’s understanding of the plain and ordinary meaning of these terms, and, based upon the parties’ arguments, we determine that no express construction of the claim terms is necessary to resolve the controversy, but address the parties’ arguments in the context of the prior art below.6” slip op. at 16

“(1) Whether Kim teaches a “video driver receiving the video signal and generating a video drive signal indicative of the video signal” We are persuaded that Petitioner has shown that the identified portion of Kim’s Figure 10 teaches the recited “video driver” and “generat[es] a video signal.” We find particularly persuasive Petitioner’s annotated comparison of Figure 4 of the ’521 patent as compared to Kim’s Figure 10 (both reproduced above), which illustrates the similarities between the ’521 patent and Kim. See Pet. 25–28. As set forth by Petitioner, Kim’s voltage at node A4 (video drive signal generated by the video driver identified in the dark green box) is supplied to the gate of transistor M31, driving the organic light emitting diode OLED by the video driver circuitry identified in the dark green box, similar to how voltage v(t) 322 (video drive signal) is supplied to the gate of transistor M1 driving the OLED 32 by video driver 32 in Figure 4 of the ’521 patent.

“such as that it is a “simpler design,” would be “an obvious design choice,” “would simplify material needs and cost,” was “well-known,” was a “trivial design change,” would “provide immunity to power source noise,” and “would allow rejection of other power supply noise, such as drift.” Pet. 68– 70. However, several of these reasons focus on what a person of ordinary skill in the art would have been able to do, rather than what a person of ordinary skill in the art would have been motivated to do at the time of the invention. See Polaris Indus., Inc. v. Arctic Cat, Inc., 882 F.3d 1056, 1068– 69 (Fed. Cir. 2018) (finding problematic that “the Board focused on what a skilled artisan would have been able to do, rather than what a skilled artisan would have been motivated to do at the time of the invention”); InTouch Techs., Inc. v. VGO Commc’ns, Inc., 751 F.3d 1327, 1352 (Fed. Cir. 2014). We find Petitioner’s arguments unpersuasive because they amount to little more than an assertion that the recited limitations could have been easily achieved. We agree with Patent Owner that Petitioner’s proposed modification of Hayafuji is a redesign that appears to be the result of hindsight rather than based upon a persuasive reason for the modification. See Sur-reply 15–18. Petitioner’s argument that the modification involves adding to the functionality of Hayafuji by using an obvious variation of the circuitry Hayafuji already discloses that eliminates both the ripple component and the non-ripple component (see Reply 20–21) supports the conclusion that the proposed modifications were improperly informed by the requirements of the claim. For example, Dr. Kattamis’s testimony describes the proposed modifications, which include removing the ripple component extraction circuit and rewiring the existing circuit. Ex. 1015 ¶¶ 270–273, 321–331. We find that the extent of the proposed modifications is more suggestive of hindsight than obviousness. See Metalcraft of Mayville, Inc. v. The Toro Co., 848 F.3d 1358, 1367 (Fed. Cir. 2017) (“[W]e cannot allow hindsight bias to be the thread that stitches together prior art patches into something that is the claimed invention.”); InTouch, 751 F.3d at 1351 (Fed. Cir. 2014) (criticizing use of the challenged patent as a “roadmap” for putting what the expert referred to as “pieces of a ‘jigsaw puzzle’” together).” slip op. at 57
